과학기술에 대한 역사적 고찰과 생산자동화기술에 대한 발전과정에 대하여 논의하였다. 현재 일차적인 우리의 과제는 지금까지 개발된 기술을 완전히 이해하여 이를 효과적인 생산시스템을 구성하는데 필요한 지혜로운 지식으로 승화시키는데 있다. 기술에 요행이 없으며 과대포장도 있을 수 없다. 기술은 있는 그대로 사회경제에 영향을 미친다. 국내의 기술실태를 고려할 때 우리들은 기반요소기술부터 복합요소기술, 대규모 software시스템 기술 및 폐기물 재활용기술에 이르기까지 거의 모든 분야의 기술을 동시에 개발 통합시켜야할 입장에 있다. 15세기 세종대왕때 우리가 누렸던 과학기술문명의 세계적인 우월성을 21세기에 실현시킬 수 있는 그날이 오기를 고대한다.

Among the tools based on generative artificial intelligence, the possibility of using ChatGPT is being explored. However, studies that have confirmed what factors should be considered when using it educationally based on learners' actual perceptions are insufficient. Through qualitative research method, this study was to derive consideration factors when using ChatGPT in the education. The results showed that there were five key factors as follows: critical thinking on generated information, recognizing it as a tool to support learning and avoiding dependent use, conducting prior training on ethical usage, generating clear and appropriate questions, and reviewing and synthesizing answers. It is necessary to develop an instructional design model that comprehensively composes the above elements.

Based on the characteristics of the weapon system, a government-funded research institute or a defense industry company is selected as the R&D supervision institution. On the other hand, research for the selection of a R&D supervision institution has not been conducted actively. This paper proposes a methodology for selecting R&D supervision institutions, such as procedure and indices. First, candidates of the index were obtained using data investigation and consulting, and five indices were deduced using Delphi. The weight of the indices was set using AHP. The high element consisted of 'Technical elements' and 'Business element'. The low element of 'Technical elements' consisted of 'Possession and readiness of critical technology' and 'Experience of similar R&D'. The low element of 'Business element' consisted of 'Base circumstance of the project', 'Risk management', and 'Will for the project'. The total weights of the indices were 'Possession and readiness of critical technology' 0.405, 'Experience of similar R&D' 0.297, 'Base circumstance of the project' 0.124, 'Risk management' 0.127, and 'Will for the project' 0.047. The indices were applied to the 00 weapon system and the result was deduced.

게임에서의 인공지능 기술은 이전에는 부수적인 요소로 인식되었으나, 컴퓨터 하드웨어 및 그래픽 기술 등이 발전하면서 가능성과 중요성이 점차 커져 왔다. 특히 최근 게임 인공지능 기술은 점점 더 발전하고 있고, 그 필요성도 중요시되고 있다. 국외에서는 일부 업체에서 게임 인공지능 기술을 상용화하여 시장 진입을 시도하고 있으며, 인공지능 기술이 적용된 게임이 인기를 끌고 있다. 그러나 국내에서는 게임 인공지능 기술의 중요성은 느끼고 있으나 기술 개발에는 초보적인 단계에 머무르고 있는 상황이다. 본 고에서는 게임 인공지능 기술의 국외 및 국내 현황을 알아보고, 게임에서 적용되고 있는 요소기술에 대하여 알아보기로 한다.

The purpose of this study is to estimate total factor productivity(TFP) growth by stochastic frontier function and to grasp contributing factors of its growth rate by decomposing the total factor productivity into efficiency change, technical progress, scale change, and allocation change. Annual growth rate of total factor productivity for 1990-2003 is 0.019 (1.9%), higher than that of overall industry (0.010). The main component of TFP growth is not efficiency change but technical progress. Contributing factors of total factor productivity growth are change of allocation efficiency in port industry, technical progress in sea-transportation industry, and change of scale efficiency in transportation-equipment industry. The change of total factor productivity shows a decreasing trend since late in the 1990s. The annual technical efficiency of port-logistics industry is less than that of overall industry. Capital elasticity for output (0.391) is higher than labor elasticity (0.227), but scale economy of port-logistics industry is 0.618, which is far from optimal scale economy.

지금에 이르기까지 직기개발을 위한 주안점은 새로운 위입시스템(water-jet, air-jet)의 개발과 지속적인 직기의 생산속도증가에 대한 각 위입요소들의 최적동작을 위한 기계요소의 개발에 주 어져 있었다. 반면에 위입동작과 직접 연관되지 않는 직기의 구성요소들은 증가하는 위입속도에 따라 각 기능의 안정성과 동작의 정확성에 대한 요구가 점차 증가되었으며, 특히 경사장력 및 이에 작용하는 기계요소들에 대한 기술적 요구수준은 과거의 북직기에서의 경우에 비교될 수 없을 정도의 한계적 상황을 만족시켜야 하게 되었다. 경사송출의 경우, 위사 1가닥이 공급될 때 마다 직물권취에대응하여 경사장력을 일정하게 유지하며, 경사의 일정 길이를 정확히 공급하여야 하기 때문에 고속 무북직기에서는 빠른 응답속도와 안정된 동작을 행할 수 있는 경사송출기구 및 장력제어시스템의 성능이 직기성능에 가장 큰 영향을 미치게 되었으며 지금까지 사용되어온 기계적 송출장치로는 한계적 기술요건을 만족시킬 수 없게 되었다. 이에 따라 근자에 이르러 경사장력제어형 장력송출장치의 응용이 크게 대두되고 있다. 이 글에서는 이러한 새로운 형태의 송출장치의 개발상황과 경사장력제어에서 해결되지 못한 문제점에 대하여 다루어 보고자 한다.

The purpose of this study is to investigate the impact of IT components of e-CRM on customer response performances in e-CRM. To this end, we classified IT components of e-CRM into the ones for customer management and the ones for customer analysis on the basis of previous studies. Also, we identified variables for customer response performances and conducted empirical analysis. The main results of this study are as following. First, this study derives the IT components of e-CRM for customer management and customer analysis respectively by reviewing the previous studies. Furthermore, this study defines business performance variables as customer response performances. Secondly, the hypotheses concerning the correlations between the use of the IT components of e-CRM for customer management and customer analysis and customer response performance are partly accepted, which shows that the use of particular IT components has significant influence on customer response performance. The findings of this study can contribute to expanding the theoretical background in the area of e-CRM adoption and development and be helpful to practical implementation of e-CRM systems in business organizations.

Architectural drawings are the records containing a lot of information about constructions and an architectural drawing has a lot of technical, physical and significant uniqueness. The most important thing required to preserve and utilize architectural drawings is description. However, there is still no standard for the description of architectural drawings in Korea. Therefore this study proposes description elements for architectural drawings based upon examining a generic character of architectural drawings and analyzing several standards and guidelines that can be used as the description rule application model for architectural drawings.
